RAJA Proxy Applications

This project contains a collection of proxy applications written using the RAJA Rerformance Portability Layer. These applications are examples of how RAJA is used in real codes and provideng a convenient vehicle for testing features and analyzing performance.

Quick Start

This repository is hosted on GitHub. To clone the repo into your local working space, use the command:

$ git clone --recursive https://github.com/LLNL/RAJAProxies.git

The --recursive argument is used to download the repository's submodules, RAJA and the build system BLT. After you execute this command, you will see the master branch in the raja-proxies directory.

Then, you can build RAJA and the proxy applications like any other CMake project, provided you have a C++ compiler that supports the C++11 standard. The simplest way to build the code is to do the following in the top-level raja-proxies directory (in-source builds are not allowed!):

$ mkdir build
$ cd build
$ cmake ../
$ make

More details about RAJA configuration options are located in the RAJA User Guide and Tutorial.

The executable for Each application will be located in the bin directory of your build space. The executable names will include the name of the proxy app, its version and parallel programming model it is using. To run an application, simply run the desired executable. For example, to run run the RAJA version of LULESH v1.0 with the OpenMP backend, execute the following command:

$ ./lulesh-v1.0-RAJA-omp.exe
